Whether you're converting a recipe, checking a fuel spec, or figuring out how many gallons are in a 2-liter bottle, this calculator handles the math. Enter any value in either field below for an instant, two-way conversion between liters and US gallons.
Type in either field. The other updates instantly. Uses the US liquid gallon.
One fixed conversion factor: 1 liter = 0.264172 US liquid gallons. Multiply liters by that number to get gallons. To reverse, multiply gallons by 3.78541.
Gallons = Liters × 0.264172
Liters = Gallons × 3.78541
Examples: 2 L × 0.264172 = 0.5283 gal. 5 gal × 3.78541 = 18.9271 L.
Liters to gallons is one line on our full metric conversion chart, which lists the factor and formula for every metric-imperial pairing.

At kitchen scale, the useful move is usually to convert cups to fluid ounces instead. And if the water bottles above have you wondering how many you should get through in a day, the water intake calculator turns your body weight into a daily target.
2 liters equals approximately 0.5283 US gallons, just over half a gallon. A 2-liter soda bottle is the most common reference point for this conversion.
1 liter equals approximately 0.2642 US gallons, about a quarter of a gallon. To be precise, 1 liter = 0.264172 US liquid gallons.
There are approximately 3.78541 liters in 1 US liquid gallon. The UK imperial gallon is larger at 4.54609 liters.
10 liters equals approximately 2.6417 US gallons. Multiply any liter value by 0.264172 for the gallon equivalent.
5 liters equals approximately 1.3209 US gallons. A 5-liter container holds a bit more than 1 gallon and a quarter.
US liquid gallon = 3.78541 liters. Imperial gallon (UK, Canada) = 4.54609 liters, about 20% larger.
This calculator uses the US liquid gallon.
Multiply liters by 0.264. For a rough mental estimate, divide by 4. The true factor is 3.785, so dividing by 4 understates slightly but is close enough for a quick ballpark.
Yes. L (uppercase) is the standard abbreviation. Lowercase l is also accepted but less common since it can be confused with the number 1. "Litre" is the British spelling of the same unit.
We built this because the conversion factor (0.264172) is annoying to remember, and Google still mostly shows pages that don't acknowledge the US-vs-UK gallon difference. One field, the other updates. Done. This site is a part of the ads4good Network.
